> The x25519 algorithm also plays a role in post-quantum safe cryptographic solutions, having been included as the classical algorithm in the TLS 1.3 and SSH hybrid scheme specifications for post-quantum key agreement.

Really though? This mostly-untrue statement is the line that warrants adding hashtag #post-quantum-cryptography to the blogpost?




Actually, e.g. rustls added X25519Kyber768Draft00 support this year: https://news.ycombinator.com/item?id=41534500

/?q X25519Kyber768Draft00: https://www.google.com/search?q=X25519Kyber768Draft00


Kyber768 is the post-quantum algorithm in that example, not x25519.


From "OpenSSL 3.4 Alpha 1 Released with New Features" (8 days ago) https://news.ycombinator.com/item?id=41456447#41456774 :

> Someday there will probably be a TLS1.4/2.0 with PQ, and also FIPS-140 -4?

> Are there additional ways to implement NIST PQ finalist algos with openssl?

Not sure what you're trying to say here . x25519 is objectively not PQC and never claimed to be, and this isn't debatable.


In this case, hybrid means "not entirely PQ".
